[0032] As shown in Figures 1-3 The utility model discloses a goods to person disassembling sorting device, including:

[0033] Warehouse shelf 10, including stand and crossbeam, stand and crossbeam can be dismantled and are connected, and the warehouse shelf 10 is stored with the box, and the box, storage location and goods are provided with one-to-one bar code;

[0034] Box robot 20 is controlled with controller control connection, is used to store and take the box in warehouse shelf 10;

[0035] Sorting work station 30 is provided with sorting table, computer, scanning gun and seeding wall 301, and the seeding wall 301 is used for the sorting of the goods in the box of sorting;

[0036] Sorting conveying line 40 is located between the first row warehouse shelf 10 and sorting work station 30, is used to convey the box that box robot 20 obtains from the warehouse shelf 10 to corresponding sorting work station 30, and transports the box that has been sorted to return to the warehouse shelf 10;

[0037] The picking conveying line 40 is located between the storage shelf 10 and the picking station 30, and comprises a first circulating conveying line and a second circulating conveying line. The first circulating conveying line comprises a first conveying line 401 driven in a first direction, a second conveying line 402 driven in a second direction opposite to the first direction, and a transfer mechanism 403 (i.e. a turning mechanism) located between the first conveying line 401 and the second conveying line 402. The first conveying line 401 is provided with a connection port, and one side of the second conveying line 402 is provided with the picking station 30. The second circulating conveying line is provided corresponding to each picking station 30, and comprises a third conveying line driven in the first direction, a fourth conveying line driven in the second direction, and a transfer mechanism 403 (i.e. a turning mechanism) located between the third conveying line and the fourth conveying line.

The above embodiment enables the large and small circulating line structure of the utility model to be modified on the basis of the existing fixed closed-loop conveying line. The large circulating line only needs to be connected to the main node, and the small circulating line is deployed using the existing space of the station without the need for large-scale hardware modification. When a new station is added, it only needs to be connected to the large circulating line and configured with an independent small circulating line without the need for reconstruction of the global conveying network.

[0038] In the process of disassembling and picking, the system issues a task of distributing a bin to the bin robot 20 and a task of recycling the bin, controls the second circulating conveying line to circulate and convey the bin in each picking station 30, and if a bin is no longer needed in the current picking station 30 and other picking stations 30 need the bin, the bin is transferred from the current second circulating conveying line to the first circulating conveying line, and then transferred to the second circulating conveying line corresponding to the picking station 30 that needs it through the first circulating conveying line. The above conveying line configuration of the embodiment enables the large circulating line to be responsible for the flow of bins between stations, realizes cross-station resource scheduling, and makes the bins globally allocated on demand; and the small circulating line enables the bins in the station to meet the reuse of orders in the station without detouring the large circulating line, shortens the picking path, and realizes fast picking.

[0044] During picking, the bin robot 20 conveys the bin to the first conveying line 401 of the small circulation line, and gradually moves the bin from the first conveying line 401 to the picking work station 30 in the order of the first conveying line 401, the second conveying line 402 and the picking work station 30 through the transfer mechanism 403 to perform bin picking work, and the picking table in the picking work station 30 can store bins, and generally can store three bins, when the storage position of the picking table is full, the fourth bin is circulated back and forth between the first conveying line 401 and the second conveying line 402 through the transfer mechanism 403, so that the accumulation and blockage of multiple bins on the picking table can be avoided, and the picking efficiency is improved.

[0045] Further, Figure 4 A connection schematic diagram of a packing circulation conveying line and a packing work station in an embodiment of the utility model is shown in Figure 4 As shown in the figure, the goods-to-person unpacking and picking device further comprises:

[0047] Specifically, the packaging and circulating conveyor line 50 is configured as a double layer, matching the double-layer seeding wall 301. When the seeding wall 301 completes the picking operation or is full, the boxes on different layers of the seeding wall 301 are sent to the corresponding layers of the packaging and circulating conveyor line 50, realizing the function of transporting goods simultaneously on both layers and improving operational efficiency. Furthermore, each layer of the packaging and circulating conveyor line 50 can simultaneously transport loaded boxes and empty boxes, enabling mixed reuse.

[0048] In this way, the setting of the packaging and conveying line 50 solves the problem of limited operation in different fire zones, expands the effective working area, and realizes the seamless connection between picking and packaging operations.

The column is vertically set on the base and fixedly connected to the base. The telescopic fork mechanism is connected to one side of the bracket. The clamping device of the telescopic fork mechanism can rotate 180° in the horizontal direction to clamp the bin and realize the storage and retrieval of the bin.

[0051] More preferably, the clamping device is configured as a retractable structure, and the robot system automatically judges the depth distance of the cargo location, thereby enabling the clamping device to extend and retract, achieving precise gripping of the material box.

[0052] By setting up multi-layer temporary storage trays, the bin robot can handle more than 20 bins, improving the picking hit rate and picking efficiency.

[0053] Furthermore, the bin robot 20 also includes a QR code navigation and laser obstacle avoidance device, which is used for the navigation, positioning and obstacle avoidance of the bin robot 20.

[0054] Specifically, the QR code navigation can accurately locate the walking path and has a strong anti-interference ability. The laser obstacle avoidance device has a detection angle of 360°, which can accurately detect the surrounding environment and efficiently avoid obstacles, thereby improving the positioning and obstacle avoidance capabilities of the bin robot 20.

[0055] Furthermore, the picking conveyor line 40 and the packaging circulation conveyor line 50 are composed of belt conveyors, roller conveyors, 90° and 180° turning roller conveyors, converging roller conveyors, lifting and transferring mechanisms, and inclined belt conveyor mechanisms.

[0056] Preferably, the sorting conveying line 40 cooperates with the sorting workstations 30 to effectively realize the goods-to-person supply, reduce the number of use of the bin robot 20, and shorten the walking time, the searching time and the picking time of the picker through the cooperation of the bin robot 20 and the sorting conveying line 40, thereby saving manpower.

[0057] Further, the seeding wall 301 is provided with an electronic tag, the electronic tag is bound with the bin, when the picker scans the barcode on the goods, the electronic tag light on the corresponding seeding wall 301 is triggered to light up, prompting the picker to place the goods in the bin corresponding to the electronic tag, and completing the sorting operation. The electronic tag can assist the picker to quickly and accurately complete the sorting task, and improve the operation efficiency and accuracy of the picker.

[0058] More preferably, a plurality of seeding walls 301 can be arranged at each sorting workstation 30, specifically two groups of seeding walls 301 can be arranged, and the two groups of seeding walls 301 can simultaneously perform sorting, thereby improving the sorting efficiency.

[0059] Further, the goods-to-person picking device of the embodiment further comprises a charging station (not shown in the figure) for charging the bin robot 20, the charging station is in control connection with the controller, and the controller can control the automatic charging and power-off of the bin robot at the charging station.

[0060] Specifically, the charging station is connected with an online automatic charging system through a WIFI network arranged in the warehouse, receives the unified scheduling of the online automatic charging system in the running state of the charging station, and transmits the running real-time state to the controller, thereby realizing the real-time dynamic monitoring of the controller on the charging station. The online automatic charging system meets the technical requirements of the power lithium battery charging, can provide reliable charging support for the 24-hour continuous operation of the bin robot 20, and ensures that the charging station has high charging efficiency, large output power, and stable and reliable charging state.

[0061] Preferably, the charging station itself has a state monitoring and protection function, can detect temperature, charging current and charging voltage, and realizes over-temperature protection, over-current protection, short-circuit protection and over-voltage protection according to the monitoring information.

[0062] More preferably, the use of the charging station is divided into an online mode and a manual mode, in the online mode, the charging station is controlled by the controller and uniformly allocates the charging for the bin robot 20, and in the manual mode, the charger in the charging station is manually controlled to charge the bin robot 20.

[0063] In order to more clearly understand each component of the goods-to-person picking device, the operation process of the goods-to-person picking device is introduced as follows:

[0064] Step one, when receiving the picking order, the operator selects the "B2B general picking station" in the WMS system to start the work, and the system will issue the order of the order picking task to the work area;

[0065] Step two, the seed wall 301 binds the empty box, and after the order picking task is issued to the box robot 20, the box robot 20 takes the box required by the picking station 30 from the storage shelf 10 and sends it to the corresponding connection port of the picking conveying line 40 in front of the picking station 30, and the box is unloaded one by one by the box robot 20, and the box is sent to the corresponding picking station 30 by the picking conveying line 40;

[0066] Step three, if the picking task of the picking station 30 is being executed, the box will circulate in the first conveying line 401 and the second conveying line 402 through the transfer mechanism 403 until the picking task of the picking station 30 is completed and then enters the designated picking station 30;

[0067] Step four, the operator scans the barcode on the box, and according to the system indication and the light prompt of the seed wall 301, the corresponding number of books is taken out of the box and placed in the grid box of the seed wall 301, and the light indicates that the box picking is completed. The box conveying line 40 conveys the picked box to the corresponding connection outlet, and the box robot 20 transports the picked box back to the designated storage location of the storage shelf 10;

[0068] Step five, when the picking personnel complete the picking of the whole order or the seed wall 301 grid box is full, the operator clicks the change box button to push the full box to the packing circulating conveying line 50 for packing, and the seed wall 301 binds a new box to continue the task.

[0069] In this way, by using the goods-to-person order picking device to complete the picking of the whole variety order, the operation mode of the whole variety order is set, which breaks through the difficulty of order picking of multiple varieties and small quantities, improves the order picking efficiency and accuracy, and reduces the labor intensity and complexity of the operation.

[0070] The goods-to-person picking device of the present application does not require the workers to spend time and effort to manually find goods, and only needs to wait at the picking station. The bin robot takes the bin loaded with goods from the storage shelf, and delivers it to the workers through the picking conveying line. This greatly reduces the labor intensity of the workers, and the picking efficiency is 3-5 times that of traditional paper picking, PDA / RF picking, etc. The picking efficiency is several times higher than the "person-to-goods" operation model. With the real-time completion of the outbound and inbound operations, the system can increase or decrease the inventory synchronously. Without manual intervention, the inventory accuracy is greatly improved. In the picking operation, the "goods-to-person" picking technology has higher accuracy than traditional manual picking, greatly improving the accuracy of logistics operations and the precision of picking. It can effectively avoid errors caused by human factors and ensure that goods are accurately delivered to consumers. At the same time, through the cooperation of the picking conveying line and the packaging circulating conveying line, the whole process can be automatically connected, efficiently operated, and precisely managed.

[0071] The above description is only the preferred embodiment of the present application and the explanation of the technical principles applied. Those skilled in the art should understand that the technical scope involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the technical concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) having similar functions to form technical solutions.
